T0 all whom t 14n/ay concern.-

Beit known that I, JEREMIAH E. REEVES, a'

citizen of the United States, residing at Canal Dover, in the county of Tuscarawas and State of Ohio, have invent-ed new and useful Im-` provements in Pair and Sheet Furnaces, of which the following is a specification.

My invention relates to improvements in combined pair and sheet furnaces; and it consists in the arrangementof parts so -that the heat from one fire chamber is conducted through the pair-furnace and thence to and through the sheet-furnace and returns to the underpart of the pair-furnace and thence to the stack and is controlled and regulated by one damper placed on top of the stack, t'nus simplifying the construction, reducing bot-h the cost of construction and the operation, and eeonomizing and utilizing all the heat, as will be hereinafter more fully described 4and claimed. A

In the accompanying drawings similar letters of reference refer to similar parts.

Figure l is a vertical longitudinal section. Fig. 2 is a sectional plan view. Fig. 3 is a foundation plan View.

A represents the fire-chamber, which is located at one end of the furnace and may be of any desired form. I have shown it provided with the usual grate-bars and ash-pit; but it may be adapted either to the use of coal, oil, or gas.

B represents the pair-furnace, supported upon an arch b, sprung from the division walls orpartitions b and b2 between the sheetfurnace and the pair-furnace and between the pair-furnace and fire-chamber, respectively. The bottom of the pair-furnace is provided withupwardly-extending parallel ridges extending transversely throughY the furnace, forming a support for the pairs. The parallel ridges b3 are formed of brick set in edgewise and extend throughout the entire length of the pair-furnace. It will be observed that the floor of the pair-furnace is located within a comparatively-short distance of the top or roof covering O of the furnace, which causes the heated gases from the firechamber to pass through the pairs which may be placed inthe furnace and at the same time permits of the construction of the chamberD under the tioor of the pair-furnace, which the pair-furnace.

communicates with the stack E by means of' lthe opning e in chamber' D, through which the heated gases pass -on their way to the stack, thus heating the under part or floor of The division-Walls b' and b2 terminate short of the roof, leaving the ap= ertures or openings h4 and b5. The roof ofthe sheet-furnace is slightly elevated above that ofthe pair-furnace and fire-chamber, and the door F of the sheet-furnace is formed substantially the same way as that of the pairfurnace, excepting that the u pwardly-extending parallel ridges or bars b3, upon which the sheets rest, extend longitudinally through the furnace. On the forward end of the sheetfurnace and upon either side thereof there are provided recessed flues G, which communicate with the ilues H under the l'loor of the sheet-furnace. Both the pair and sheet furnaces and likewise the fire-chamber are provided with the usual form of doorways or openings J, and the furnace has the usual buck-stays for holding the casing thereoftogether andto the furnaces.` The foundation I may be built of concrete or brick.

In operation the lire is started in the firechamber and the damper on the stack opened, when the heat passes up andinto the pairfurnace and thence into the sheet-furnace, and by means of the recessed titles is thence conducted down to the tlues underneath the sheet-furnace, which communicates with the chamber under the pair-furnace, and thence into the stack, utilizing by the means thus employed all the heat and keeping all the parts of the furnace heated.

It will be observed that by this form of con-` struction the number of attendants necessary to operate the furnace is reduced, there being no dampers intervening between the Various parts of the furnace requiringthe services of an employee for their operation, and the fire from one re-chamber furnishes the heat for both furnaces, thus reducing the expense of operating the furnace, and having but one damper located on the top of the stack operated by the sheet-heater, thus preventing the pair-heater from overheating and scaling the pairs in the pair-furnace andfrom scaling the sheets in the sheet-furnace, which frequently occurs in furnaces having a series of dampers operated by different employees.

IOO

It will also The combination in a reheating-furnace, of

a fire-chamber, an elevated pair-chamber communicating therewith, an elevated sheetchamber directly communicating with the pair-chamber, the floor of .thevsheet-heating; chamber downwardly inclined toward vand terminating adjacent 4to the pair heating chamber, a return-flue underneath and parallel to the doors of the sheet and pair chambers; andof a Width equal thereto, and communicating with a stack at the side of the pair-chamber, substantially as described and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
